<p>Announcing the release of <code class="language-plaintext highlighter-rouge">camkes-3.2.0</code> with the following changes:</p>

<p>camkes-3.2.0 2018-01-17</p>

<p>Using seL4 version 8.0.0</p>

<h1 id="changes">Changes</h1>

<ul>
  <li>
    <p>New ADL Syntax: Allow struct elements to have defaults.</p>

    <p>See the following ADL files for examples of Struct and
  Attribute behavior.

  </li>
  <li>
    <p>Added experimental Rumprun support:</p>

    <p>This functionality is experimental and may not work
  as expected. See the following examples:
  <a href="https://github.com/seL4/camkes/tree/master/apps/rumprun_ethernet">https://github.com/seL4/camkes/tree/master/apps/rumprun_ethernet</a>
  <a href="https://github.com/seL4/camkes/tree/master/apps/rumprun_hello">https://github.com/seL4/camkes/tree/master/apps/rumprun_hello</a>
  <a href="https://github.com/seL4/camkes/tree/master/apps/rumprun_pthreads">https://github.com/seL4/camkes/tree/master/apps/rumprun_pthreads</a>
  <a href="https://github.com/seL4/camkes/tree/master/apps/rumprun_rust">https://github.com/seL4/camkes/tree/master/apps/rumprun_rust</a></p>

    <p>More information about the Rumprun unikernel on seL4 can be
  found here:

  </li>
  <li>
    <p>New Templates: Remote GDB debugging support</p>

    <p>On ia32 platforms a GDB server can be used to debug a
  component using the GDB server remote serial protocol.
  documentation:
  <a href="https://github.com/seL4/camkes-tool/blob/master/docs/DEBUG.md">https://github.com/seL4/camkes-tool/blob/master/docs/DEBUG.md</a></p>
  </li>
  <li>
    <p>Added “hardware_cached” attribute to hardware dataports</p>

    <p>This feature had been added to camkes-2.x.x but hadn’t been
  forward ported to camkes-3.x.x. documentation:
  <a href="https://github.com/seL4/camkes-tool/blob/master/docs/index.md#cached-hardware-dataports">https://github.com/seL4/camkes-tool/blob/master/docs/index.md#cached-hardware-dataports</a></p>
  </li>
</ul>

<h1 id="known-issues">Known issues</h1>

<ul>
  <li>Hardware dataports that are large enough to use larger frame
      sizes are currently broken. There is an issue with</li>
</ul>

<p>large frame promotion and hardware dataports where the capDL loader is
unable to map the promoted memory. This can be demonstrated by running
the testhwdataportlrgpages app on either
arm_testhwdataportlrgpages_defconfig or
x86_testhwdataportlrgpages_defconfig configurations. If this
functionality is required, hold off upgrading until this issue is fixed.</p>

<h1 id="upgrade-notes">Upgrade notes</h1>

<ul>
  <li>ADL files: ADL syntax changes in this release should not break
      any existing ADL files.</li>
  <li>

    <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>Templates:

    seL4HardwareMMIO template now has an option to map hardware
    memory as cached. The default setting is uncached
</code></pre></div>    </div>
  </li>
</ul>

<p>which is the same as the old behaviour.</p>
